Ask a question about Sylvania GNET13001

I received my Sylvania notebook but it was not preloaded with any OS, I attempted to load a Linux OS, Ubuntu Remix on, but that crashed during installation, I then attempted Windows XP which also blue-screened and even Windows 7 which actually completes the loading process but upon reboot for the first time, goes to a black screen stating that 'Operating System not found". I've tried to redo the MBR thinking that this might be corrupt (even though there's never been anything loaded onto it) but to no avail. Any help?
